How do I set up a bass after switching to flatwounds?

Question

Accepted Answer

After fitting flatwounds, let them settle, then check relief, action and intonation. Flatwounds run firmer than roundwounds of the same gauge, so the neck often needs a small truss rod adjustment to reduce relief. Don't cut flatwound strings: choose the correct length so they fit without trimming, then intonate each string before playing. Flatwounds are a popular switch, especially on a Precision Bass or fretless. They feel smoother and sound deeper, and the setup needs a quick recheck.Before installing:Confirm the length. Our Power Flat Flat Wound Bass sets are standard long scale, about 37.25" usable winding length, which fits most 34" basses. Measurements are approximate.Do not cut flatwounds. Wind them on at their full length.Setup steps:Install, tune and settle the strings over a day or two.Check relief. The firmer strings may pull more bow into the neck. Tighten the truss rod slightly if needed, or ask a tech.Set action at the bridge saddles to taste. Flatwounds can be set slightly lower without as much finger noise.Set intonation on each string using the 12th-fret harmonic and fretted note.Balance pickup height by ear, since flatwounds have fewer high overtones.S.I.T. Power Flat sets are PF45105L (4-string), PF545130L (5-string) and PF630130L (6-string). For a halfway point that keeps more brightness, our Semi-Flat Silencers Bass sets such as NRL45105L cut finger noise with less change in feel.
